when to switch car seats

Hannah • Hey my name is Hannah. I am a 27 yo SAHM 💙👶🏻 💙4/29/16 💙👶🏻 💙4/23/18
My son is 9 months and almost 24 pounds. My Eddie Bauer car seat has a weights limit of 35 pounds but my son looks like he is getting too big for it. Should I switch out to another car seat or should his carrier be fine until he is 35 pounds?
